There is the electromagnetic force that keeps machines going, make chemicals react and that makes your monitor work.

And then there is gravity.

Gravity is an omnipresent force, we always feel it, and we generate it ourselves. Where there is matter - there is gravity, an axiom as true as any.
But gravity is a weak force. So weak it takes the entire influence of the earth to keep a paper to the table.

The only places where gravity show it's real power are in the vicinity of black holes - the almost mythical stellar abominations. At the event horizon - the distance from the hole at which nothing can escape - gravity is so strong that relativity interferes with any attempt to reach escape velocity. Not even the black hole can escape it's own wrath and it get inexorably sucked into itself until space no longer makes sense. Matter... cease. It turns into a singularity, a point in space, an infinitely small area at the edge of reality. There the laws of the universe no longer apply, because the universe have ended. The energy in the matter have been converted into a space-time distortion, an indentation in the universe.

The hole still have kinetic and electromagnetic energy. The singularity do possess a spin (something that should be impossible when considering a 0 dimensional point, but as said before, the universe simply stop caring) which crabs a hold the surrounding space-time and rotates it.
The hole also have an electromagnetic charge. These are referred to as "hair". It was said that a black hole doesn't have hair, that it they are completely uniform and the only thing that make on different from another are it's mass. With the exceptions of charge and spin this is true.

But if the only instance where gravity is really strong compared to how big the input of matter is (the singularity is very small) couldn't one draw the conclusion that singularities are the only "true" form of matter. Normal matter only makes bulges in the space continuum whilst full fletched singularities pokes through.

If that is so wouldn't that mean that our world are located in the twilight-zone between vacuum and the real world. What we see as matter should be considered as mere virtual matter. In our universe there is a constant flux of virtual particles, creasings in space-time that pop up as particle-pairs and then pop back into the vacuum before they can be detected.
The real matter in our world do something similar. It floats around without being able to do very much on a "hypothetical macro-dimensional" (don't quote me on that stupid fictional term) basis. However if enough of it is collected it will implode to a black hole.

So our world is only half-existing, and in it there is half-existing particles (virtual particles). Does this mean that there is an infinite number of levels of existence, where every state of matter got particles that can't affect it and this matter as well have sub-particles that can't affect it.

The virtual particles in our world can be pulled into existence if they appear next to an attractive force. If a virtual particle-pair (they always come in pairs) appears next to a - for example - black hole and one particle is drawn towards it while the other manages to escape then they can't pop back and are therefore suddenly real particles. The energy needed is taken from the black hole and it is through this process black holes slowly evaporate. It takes a long time and even an incredibly small black hole created at the birth of the universe wouldn't be completely evaporated by today.

So real matter can be created from virtual particles, and black holes - the really real particles - can turn back into normal matter. Does this mean that normal matter can be converted back into virtual particles? That our world is decaying into semi-existence?

This sort of decay and creation might explain why the virtual particles seems to constantly fluctuate in and out of existence instead of remaining in equilibrium as normal matter. The virtual particles are being created and decays very rapidly.

This is a another way of looking at the old and widespread theory of how we are just a small part of a greater macrocosm, even though I have avoided to make references to it before since it is still important to understand that that is not what I have been trying to discuss.

Matter might not be as stable and everlasting as we perceive it to be. Atoms might silently evaporate in front of you in this very moment. However, if we presume that the time it takes for a atom to evaporate is in the average of the decay of a black hole and a virtual particle still puts the decay-time of matter somewhere .

It makes you wonder.
